Definitions

  • the present invention relates to a portable, hand-held pump and in particular a pump for filling objects with gases such as air.
  • Pumps used to fill objects to a high pressure typically incorporate reciprocating air compressors. These types of compressors tend to be large and heavy in size and require an external power supply. This in turn makes such pumps difficult to transport and less useful if an external power supply is not readily available.
  • a potential limitation noted by the Applicant in relation to their invention described in Patent Application WO2017/015711 is that it is impractical for a cyclist to carry the unit in their cycling jersey pocket, given the relatively large size of the unit.
  • the relatively large size is mainly due to the use of a bulky gear assembly to drive the compressor via the brushless motor.
  • a hose and fitting arrangement is provided to supply compressed air from the unit to the tyre.
  • the inflation time of the pump described in Patent Application WO2017/015711 is very sensitive to the compressor's compression ratio. Very high compression ratios are required to reduce the inflation time of a bicycle tyre.
  • the high compression ratios require clearances smaller than 0.2mm between the compressor's piston and the top of the compressor's cylinder when the piston is at top dead centre, and such clearances can only be achieved using expensive CNC machining processes. This adds significant time and cost to manufacturing of the compressor parts, which is undesirable.
  • EP 1 003 971 A2 discloses a two stage reciprocating compressor and associated HVAC systems and methods, wherein the reciprocating compressor includes a crankshaft having an eccentric crankpin, a reversible motor for rotating the crankshaft in a reverse direction, and an eccentric, two position cam rotatably mounted over the crankpin.
  • the clearance at the top dead centre (c) is preferably between 0.2 and 1.5mm (and more preferably between 0.2 and 1.0mm), the inner cylinder diameter (d) is preferably between 12.0 and 18.0mm (and more preferably between 12.0 and 20.0 mm), and the piston stroke (s) range is preferably between 10.0 and 14.0mm.
  • the power supply is a rechargeable battery having a nominal voltage of between approximately 7 and 12 volts, a C rating of at least approximately 25, and a capacity of between approximately 200 and 600mAh.
  • the battery may be a lithium polymer battery, a lithium-ion battery, or the like.
  • these batteries are also easy to recharge through use of an external power source such as a wall adaptor, and the batteries do not need to be removed from the unit to recharge them. Nevertheless, other suitable battery types may also be utilised.
  • the electric motor is preferably a brushless DC motor having a motor diameter of between approximately 25 and 35mm (although a diameter between approximately 20 and 30 mm has previously been contemplated), a torque range of between approximately 100 and 300mNm (although a torque range between approximately 100 and 200mNm has previously been contemplated), and capable of operating at a speed of at least approximately 550 rpm/V when subjected to a compressor load.
  • the electric motor is preferably a brushless DC motor, as opposed to a brushed DC motor of the type commonly found in typical air pumps - as brushless DC motors have much higher torque-to-weight ratios compared to conventional brushed DC motors. This allows for a smaller sized (and hence, lighter) motor to be used, whilst still providing enough torque to drive the compressor.
  • the pump preferably has a total weight of less than approximately 400 grams (although embodiments with less than approximately 250 grams have also been contemplated by the applicant), and can pump up at least one bicycle road bike tyre to approximately 100psi on a single charge.
  • the housing preferably has a length of between approximately 55 and 95mm (although lengths between approximately 55 and 75mm have been previously contemplated by the applicant), a height of between approximately 50 and 70mm, and a width of between approximately 30 and 45mm (although widths of between approximately 25 and 35 mm have been previously contemplated). It is to be appreciated that these dimensions provide an extremely compact pump that can be easily carried in a cyclist's jersey pocket.
  • the outlet is provided on or mounted to the housing.
  • the outlet preferably includes a collar extending outwardly from the housing, with the collar including a valve receiving bore for receiving a valve of the object (such as a tyre) to be pumped.
  • a valve of the object such as a tyre
  • the outlet that connects the reciprocating air compressor to the valve does not utilise a hose.
  • the pump would therefore mount directly onto the tyre's valve.
  • the pump can be manufactured compactly enough to fit between the spokes of a bicycle wheel, thereby enabling it to be directly mounted onto a bicycle tyre valve.
  • the housing is made from a high strength, thermally conductive material such as aluminium.
  • the housing is preferably in contact with a portion of the pump's compressor, thereby acting as a heat sink. It does this by removing heat from the compressor via conduction. This arrangement adds negligible weight to the compressor whilst increasing the compressor's maximum run time and duty cycle.
  • a high strength material such as aluminium, as opposed to low strength materials such as plastics, allows the housing to be manufactured with thin walls, thereby reducing the overall size of the pump.
  • the present invention improves on past approaches, as its design has been optimised for use as a pocket-sized, or miniature device that can pump up a bicycle tyre in less than a minute, can engage directly onto a bicycle tyre's valve without use of a hose and fittings, yet can be manufactured from cheap manufacturing processes such as casting processes. Further to this, the pump weighs less than 400 grams so as to not hinder the cyclist from a weight perspective. Accordingly, the pump of the present invention could be described as being "miniature" in size when compared to existing pump designs.
  • FIGS 1 and 3 to 5 show a portable pump 100 according to the present invention.
  • the portable pump 100 includes a power supply 102, and an electric motor 104 having a drive shaft 106 that connects directly to a reciprocating air compressor arrangement 108.
  • the drive shaft 106 is rigidly mounted to the crank 122, with the rotation axes of the drive shaft 106 and the crank aligned along X-X (shown in Figure 1 ).
  • a control unit 110 is provided, which is in electrical communication with the electric motor 104, and the power supply 102.
  • the power supply 102, electric motor 104, drive shaft 106, reciprocating air compressor arrangement 108 and control unit 110 are all contained within a housing 112.
  • the control unit 110 may be a printed circuit board that consists of control circuitry that turns the motor ON and OFF via switch 114, and monitors the battery's voltage.
  • the reciprocating air compressor arrangement 108 includes a number of components which allow for the portable pump 100 to be miniature in size.
  • the reciprocating air compressor arrangement 108 includes a cylinder 116, as well as a piston 118 connected to a connecting rod 120.
  • the connecting rod 120 is connected to a crank 122 which is driven directly by the motor's drive shaft 106, rather than the drive shaft 106 driving the crank 122 via a gear assembly.
  • the piston 118 preferably further includes a sealing arrangement (not shown) which ensures compressed air is maintained within the cylinder 116 during the compression process.
  • the portable pump 100 is turned on by a user via switch 114. Once turned on, the electric motor 104 starts running which, in turn, rotates the drive shaft 106. The rotating drive shaft 106 turns/rotates the crank 122, causing the connecting rod 120 and piston 118 to reciprocate axially within the cylinder 116.
  • One-way valves (not shown) located on the top surface of the piston 118 as well as inside the compressor head 124 ensure that air is compressed inside the cylinder 116 and forced through the outlet 126. This process is carried out many times a second as the piston 118 axially reciprocates within the cylinder 116.
  • the arrangement of the portable pump 100 allows it to be manufactured small enough so that it can be mounted directly onto a tyre valve.
  • the pump 100 can be considered to be of a miniature size when compared to existing pump designs. This means that no additional hose or fittings are required to transfer the compressed air to the tyre, as the pump can fit between most conventional 700mm diameter bicycle wheel spoke configurations and directly onto the tyre valve, thereby further reducing the size and weight of the pump 100.
  • the pump 100 is manufactured without a gearbox or outlet hose, and so this enables the pump 100 to be of a very small size when compared to existing pump designs.
  • the pump 100 has a length only in the order of approximately 55 to 95mm, a height of only approximately 50 to 70mm and a width of only approximately 30 to 45mm. These small dimensions allow the pump to fit easily into a cyclist's jersey pocket.
  • the compressor's compression ratio needs to be optimised so that a small, brushless motor can be utilised, while achieving a pump up time of less than 1 minute.
  • the diameter of the brushless motor must be small enough so that it fits inside the pump, and therefore motor diameters ranging from 25-35mm need to be considered.
  • low cost 25-35mm diameter brushless DC motors that are fitted with rare earth, permanent magnets can achieve motor torques ranging from 100 to 300mNm. Therefore, the compressor should be designed so that it can be driven by a motor that can produce this level of torque.

  • Equation (8) can be simplified to the following design equation, which can be used to optimise the compressor's critical dimensions d, s and c to ensure the chosen brushless motor can provide sufficient torque: 1500 ⁇ ⁇ ⁇ 3800

  • Brushless motors of 25-35mm diameter when driven with 7-12 volts could easily achieve pump up times of less than 60 seconds, provided the brushless motors were designed to rotate at speeds equal to, or greater than 550rpm/V under compressor load.
  • the 7-12 volt voltage requirements allow the pump to be powered from either a 2-cell or 3-cell high discharge lithium battery.
  • FIG 3 shows the miniature pump 100 in isometric view.
  • Charge port 128 allows the use of an external charger to charge the pump's internal battery.
  • Figure 4 shows the miniature pump 100 when engaged onto a valve 128 of a bicycle tyre 130 via the pump's outlet 126.
  • the pump's outlet 126 can be replaced by an optional hose.
  • the battery 102 must be small enough to fit inside the housing 112 of the pump 100, yet be able to provide enough current to pump up at least one bicycle tyre before a recharge is required.
  • the battery 102 must also be able to handle the high currents required to drive the compressor arrangement 108, without affecting is performance, or worse, being damaged due to excessive current draw.
  • Equation (13) is the motor's speed (in units rpm/V).
  • Equation (15) suggests the pump's battery must have a capacity of at least 200mAh.
  • commercially available high-discharge lithium batteries with C ratings greater than 25, and with capacities ranging from 200-600mAh were able to fit inside the housing 112 of the pump 100, assuming the dimensions of the housing 112 ranged from 55-95mm in length, 50-70mm in height and 30-45mm in thickness. It was also determined that batteries of these capacities were able to pump up at least one road bike tyre to 100psi without the need to be recharged.
  • FIG. 5 has been provided for purely comparative purposes, to further highlight the small (ie. miniature) size of the pump 100.
  • a cyclist carrying the pump 100 in a rear pocket of their jersey would require similar pocket space as when carrying two CO2 canisters C and the associated adaptor/connector A.
  • the cyclist should be easily able to carry the pump 100 instead of the canisters and adapter.
